Objective To observe the efficacy and safety of Ginkgo biloba extract combined with Nimodipine on patients with acute cerebral infarction.Methods 106 cases of acute cerebral infarction were randomly divided into two groups(control group and treatment group),the control group was given Nimodipine on the basis of regular treatment,and the treatment group was given Ginkgo biloba extract combined with Nimodipine on the basis of regular treatment.Results The total effective rate of treatment group was higher than that of the control group (x2 =3.62,P <0.05),improvement of neurological deficit was better than that of the control group (t =2.57,5.32,all P < 0.05),Plasma TC and TG levels were significantly lower than that of the control group(t =4.23,6.43,all P < 0.05).During treatment,patients had no serious adverse reactions.Conclusion Ginkgo biloba extract and Nimodipine have synergistic effects,the two combined treatment of acute cerebral infarction have significantly effects,which is safe and reliable.
2. Anti-complementary anthraquinones from Polygonum cuspidatum and their action targets
Chinese Traditional and Herbal Drugs 2013;44(18):2502-2507
Objective: To study the anti-complementary anthraquinones from Polygonum cuspidatum and their action targets. Methods: The anti-complementary activity-directed isolation was carried out with the hemolysis test as guide. All isolates were evaluated for their in vitro anti-complementary activities. The action targets of the main bioactive constituents were also examined using complement-depleted sera. Results: Ten anthraquinones and three other compounds were isolated from the EtOAc fraction of P. cuspidatum extract, including physcion (1), chrysophanol (2), questin (3), emodin-8-O-β-D-glucoside (4), emodin (5), rhein (6), fallacinol (7), citreorosein (8), xanthorin (9), isorhodoptilometrin (10), 2, 5-dimethyl-7-hydroxychromone (11), 7-hydroxy-4-methoxy-5-methylcoumarin (12), and 5, 7-dihydroxy-1-isobenzofuranone (13). Compounds 9 and 10 were isolated from the the plants of Polygonaceae for the first time, and compound 9 was the alizarin-type anthraquinone first obtained from P. cuspidatum. Compounds 3-9 showed the anti-complementary activity in different degrees, and compound 7 exhibited the most significant activity against the classical and alternative pathway [CH50 = (6 ± 2) μg/mL, AP50 = (50 ± 5) μg/mL]. The study on the preliminary mechanism revealed that compound 4 interacted with C1q, C2, and C9 in complement activation cascade, while compound 7 acted on C1q, C2, C4, and C9. Conclusion: The anthraquinones are main anti-complementary constituents in P. cuspidatum; and fallacinol (7) is a potential complement inhibitor with strong activity and definite targets, which should be further studied in future.
3.Magnetic resonance imaging diagnosis of hilar cholangiocarcinoma
Chinese Journal of Digestive Surgery 2013;(3):196-199
Hilar cholangiocarcinoma (HCCA) or Klatskin tumor is a scirrhous adenocarcinoma that arises from the conjunction of bile duct and hepatic ducts.Hepatic magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography (MRCP) are important methods for the diagnosis of HCCA.In this article,the clinical data of 42 patients in the Changhai Hospital and 18 patients in the Eastern Hepatobiliary Surgery Hospital who received MRI and MRCP examination from October 2010 to October 2012 were retrospectively analyzed.According to the pathological features,HCCA could be divided into mass-forming type,infiltrating type and intraductal type.Based on the results of imaging examination and intra-and postoperative pathological examination,Bismuth-Corlette types were decided pre-and postoperatively.The coincidence rate of pre-and postoperative Bismuth-Corlette types was 89.7% (35/39).Infiltration of liver parenchyma was both detected pre-and postoperatively in 19 patients (16 patients were detected by MRI preoperatively),and the sensitivity of MRI was 84.2% ; vascular invasion was both detected pre-and postoperatively in 10 patients (12 patients were detected by MRI preoperatively),and the sensitivity of MRI was 83.3% ; hilar and retroperitoneal lymph node metastasis was both detected pre-and postoperatively in 6 patients (4 patients were detected by MRI preoperatively),and the sensitivity of MRI was 66.7%.Combined application of different sequences and techniques of MRI is helpful in the diagnosis,staging and treatment of HCCA.
4.Research on study attitudes of military medical university undergraduates
Chinese Journal of Medical Education Research 2011;10(5):551-553
Objective To research on study attitudes of military medical university undergraduates. Methods The study attitudes of all the undergraduates were investigated and compared in different sorts by using homemade questionnaires. Results The general study attitudes of military medical university undergraduates were good. The undergraduates of different grades had not different study attitudes, neither did the undergraduates of different ages. The undergraduates of different sorts had different attitudes, so did the undergraduates of different genders and different specialties. Concretely, the undergraduates not recruited by Army, the men undergraduates, the undergraduates of long academic-year program and five-year military medico have better study attitudes. Conclusion The general study attitudes of military medical university undergraduates were good but there is still some space to boost. All sorts of steps should be taken to correct their study attitudes and advance their study effects.
5.Study on n-Hexane-induced Lipid Peroxidative Injuries in Rats
Journal of Environment and Health 2001;18(2):86-88
Objective To study the mechanism of toxicity of hexane. Methods SD rats inhaled 15 g/ma n-hexane statically for 8 hours. Results The levels of GSH in whole blood of rats declined significantly (t-test,P<0. 01). The levels of MDA in serum of rats revealed increasing trend but without statistical significance (t-test,P>0. 05). The activities of SOD and GSH-Px in liver of rats decreased significantly (t-test,P<0.01). Conclusion n-Hexane could induce or enhance the reaction of oxygen free radical in organism,and result in damages of lipid peroxidation,which might be one of the mechanisms of the toxicity of alkane.

8.Advances in breast cancer clinical research
China Oncology 2001;0(05):-
New theory, technology and drugs have stinulated clinical research of breast cancer. The typical method for early detection of breast cancer consisted of self examination, clinical breast examination by a health professional and mammography, both fiberoptic ductoscopy and ductal lavage cytology could be effective supplements. Sentinel lymph node biopsy is a potential means of avoiding axillary dissection in women with clinically negative axillary patients without influencing the survival. New drugs and regimes had improved complete response in neoadjuvant setting so as to further treatment. Breast conserving therapy with local excision and radiation is well established as an option in the treatment of localized breast cancer, but social and economic factors of the patients should be considered aside from pathological and clinical factors. It is evident that emphasis on early detection, systemic treatment as well as more limited surgery are the trend of breast cancer treatment today.
9.Progress in diagnosis and treatment of lung cancer in the elderly
Cancer Research and Clinic 2008;20(5):353-356
Lung cancer is the most common cancer and the leading cause of cancer-related deaths in the world. More than 50 % of advanced NSCLC are diagnosed in patients older than age 65 years. Aging is inextricably associated with decreases in marrow reserve, drug clearance, and lean body mass. Elderly cancer patients often present with medical and physiologic challenges that make the selection of their optimal treatment daunting. This article reviews the progress in diagnosis and treatment of lung cancer in the elderly in recent years.
10.Reclassification of obesity and diagnosis of obesity based on individuals′ metabolic status
Chinese Journal of Endocrinology and Metabolism 2015;(8):655-658
Obesity has been widely accepted as a metabolic disease and its occurrence is closely related to the genetics, environment, and inflammation. Up to now, body mass index is still regarded as the standard diagnostic criterion for obesity. It has not been revised for decades and could not meet the needs of clinical diagnosis and demands for specific treatment at present. In 2013, the concept of metabolic obesity was introduced at the American Diabetes Association ( ADA) annual conference, and it was further proposed that obesity should be classified according to the metabolic status and its related complications at the 2014 American Association of Clinical Endocrinologists ( AACE) annual conference. This means that scientists and clinicians have realized that the etiology of obesity may vary with different outcomes, the treatment should be focused on the metabolic regulation, not merely on weight loss. With years of clinical practice and research in obesity, we have observed and treated numerous obese patients, and we have found that obesity has a lot of phenotypes and clinical features which are related to the metabolic status. Based on our clinical findings, combined with the experience of Chinese traditional medicine, we now propose a new clinical classification and diagnosis of obesity based on individuals′ metabolic status, which, we believe, can facilitate clinicians′practice. Based on the metabolic status and skin features of obese patients, obesity is divided into metabolic healthy obesity (‘white obesity’) and metabolic unhealthy obesity. Then, the latter is further divided into three groups including high metabolic obesity (‘red obesity’ ) , low metabolic obesity (‘yellow obesity’ ) , and severe metabolic disorder with inflammation obesity (‘black obesity’ ) . If we also consider to add normal weight metabolic obesity to this classification, there should be five types of obesity to be classified as presented. We wish this proposed classification of obesity can play a valuable role in enabling clinicians to have a better understanding of obesity in relation to its metabolism, and to develop individualized treatment according to the metabolic status of the patient. As a result, we may finally achieve the desired outcomes through making appropriate diagnosis and treatments.
